[SCSI] hpsa: Inform controller we are using 32-bit tags.
Controller will transfer only 32-bits on completion if it knows we are only using 32-bit tags. Also, some newer controllers apparently (and erroneously) require that we only use 32-bit tags, and that we inform the controller of this. Signed-off-by: Stephen M. Cameron <scameron@beardog.cce.hp.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
